[MacGLQuake] main source of slowdown in GlQuake

[The Greenwood's]

Dynamic lights kill the frame rate with a sledgehammer (or perhaps a rocket
launcher? :).  It's as simple as that.  Thankfully, the gl_flashblend 1
implementation is better than it was in RAVE Quake.  To be sure, dynamic
lights hurt the frame rate on any other version of Quake, but the effect is
very visibly noticeable in MacGLQuake.  I have no idea why exactly this
happens.

One other rendering "bug" I've seen is that the textures seem much more
heavily mipmapped than they ever did in RAVE Quake.  Kinda like bilinear
vs. trilinear filtering in Quake 3.  Actually, I bet that's it.  Did RAVE
Quake run in trilinear filtering?  Maybe it's not fair to compare OpenGL
and RAVE...
